采用二维脉冲Doppler超声心动图测定20例正常人和53例无生室肥厚(或)扩大的高血压病患者的左房内径和左室舒张功能。其结果表明,高血压病和正常组间,左房内径和左室舒张功能均有显著差异。高血压组左房内径增大、左室舒张功能降低,且二者间有显著正相关.高血压病左房增大出现在左室肥厚(或)扩大之前,是心脏受累的一早期改变。其左房的增大可能是左室顺应性降低所致.
Left ventricular diastolic function and left ventricular diastolic function were measured in 20 normal subjects and 53 hypertensive hypertensive patients with or without hypertrophy by using two-dimensional pulsed Doppler echocardiography. The results show that hypertension and normal group, left atrial diameter and left ventricular diastolic function were significantly different. Hypertension group left atrial diameter increased left ventricular diastolic function decreased, and there was a significant positive correlation between hypertensive disease left atrial enlargement appears in the left ventricular hypertrophy (or) before the expansion of the heart involved in an early change. The left atrial enlargement may be due to reduced left ventricular compliance.
